GoPros make terrible dashmount cameras since they lack important features like automatic saves when a crash occurs. My older GoPros also had really useless implementations of rolling recording (I'm not sure if that's fixed on the current models, but it wouldn't clean up the rolling recording from previous sessions).

They are great for bicyclists and motorcyclists who need a camera that will survive a direct impact with the ground.

They're also the best devices for simply filming your ride in any context where your main concern isn't people crashing into you.

Hey, if you're not dropping your dual sport every once in a while, you're not having enough fun on the trail! :)

Yes. For car/motorcycle, I also want external power (not all gopros have it) and a setting to start recording on powerup, so it's always on when the vehicle is powered. Plus overwrite mode, save current clip if crash, save if "i like this" button is pushed, etc.

I feel like they have all the tech components to offer a dash product with minimal work.

I have a Hero8 and it works fine for this. Rolling recording with a large memory card means it keeps stuff for a long time.
